Hello everyone. My name is Brian and I am new here. I am in need of a slip angle sensor and thought the PIXY might work for me.
Description of a slip angle sensor: A slip angle sensor is designed to mount solidly to a vehicle’s suspension, point at the ground, take pictures of the pavement passing below the car and calculate the angle between the direction the wheel is pointed and the direction the wheel is traveling (this angle is mostly due to the tires being big squishy rubber doughnuts and twisting and slipping over the pavement), hence “slip angle”.
I had in mind using a PIXY and arduino to log this angle and a few other things to an sd card. The PIXY needs to look at two consecutive images, pick an object and calculate the position of the object in the two images. I can send these x,y positions to the arduino and calculate the angle between the two points. The tough part is the fact that it will be looking at pavement (which is mostly black with little bits of random white dots) and not some red ball on a random background. I want to know if this is possible? I am willing to mount a bright light to shine on the pavement if that will help.
I have thought about painting a bunch of red dots on the pavement and tracking those, but that would be very impractical.
I have also had the thought that using a long shutter speed would result in an image full of lines that would represent the slip angle (compare these lines to a vertical line to get the slip angle). Is there a way I could use a long shutter speed, “trace” the line using the PIXIE and send that info back to my arduino?
Thanks to anyone who can help me out!
Brian
